How to improve ECShop website speed? Solve the problem from the root

Title: How to improve ECShop website speed? To solve the problem from the root cause, you need specific code examples

With the rapid development of the e-commerce industry, ECShop, as a popular open source e-commerce system, is widely used in many websites. However, as website traffic increases and functionality continues to expand, website speed becomes even more critical because both user experience and search engine rankings are closely related to website speed. So, how to improve the speed of ECShop website? This article will start from the root cause, explore some specific optimization methods, and provide corresponding code examples.

1. Optimize database queries

The database is one of the key factors in website speed, so optimizing database queries is an important way to improve website speed. Database queries can be optimized in the following ways:

  • Use indexes: Creating indexes for frequently queried fields can effectively improve query speed. In ECShop, you can add an index to a field through the following code example:

    ALTER TABLE `ecs_goods` ADD INDEX `idx_goods_id` (`goods_id`);
  • Avoid unnecessary queries: When writing SQL statements, try to avoid using SELECT *, but clearly specify the required fields to avoid querying unnecessary data.
  • Reasonable use of cache: You can use the cache function provided by ECShop to cache some frequently accessed data and reduce the number of database queries. For example, the product information can be cached into a file through the following code example:

    $data = serialize($goods_info);
    $result = file_put_contents('goods_cache.txt', $data);

2. Image optimization

The image is the loading speed of the website One of the important factors is that overly large images will increase website loading time. Therefore, you can optimize images in the following ways:

  • Compress images: Use tools such as TinyPNG to compress images on the website to reduce image file size and thereby improve loading speed.
  • Use the appropriate image format: Choose the appropriate image format according to the image content, such as PNG for icons and transparent images, and JPEG for photos.
  • Lazy loading of images: The image is only loaded when the user scrolls to the location of the image, which can reduce page loading time. Lazy loading of images can be achieved through the following code example:

    <img  data-src="image.jpg" class="lazyload" / alt="How to improve ECShop website speed? Solve the problem from the root" >
    <script>
    document.addEventListener("DOMContentLoaded", function() {
    var lazyImages = [].slice.call(document.querySelectorAll("img.lazyload"));
    if ("IntersectionObserver" in window) {
      var lazyImageObserver = new IntersectionObserver(function(entries, observer) {
        entries.forEach(function(entry) {
          if (entry.isIntersecting) {
            var lazyImage = entry.target;
            lazyImage.src = lazyImage.dataset.src;
            lazyImage.classList.remove("lazyload");
            lazyImageObserver.unobserve(lazyImage);
          }
        });
      });
      lazyImages.forEach(function(lazyImage) {
        lazyImageObserver.observe(lazyImage);
      });
    }
    });
    </script>

3. CDN acceleration

Using a content distribution network (CDN) can effectively accelerate the website access speed, especially for global websites. You can integrate CDN into the ECShop website through the following steps:

  • Configure domain name resolution at the CDN service provider and obtain the corresponding CDN acceleration link.
  • Modify the static resource link in the ECShop background and point the resource reference to the CDN acceleration link, for example:

    <link rel="stylesheet" type="text/css" href="//cdn.example.com/style.css" />
    <script src="//cdn.example.com/script.js"></script>

Through the above method, the ECShop website can be significantly improved The loading speed improves the user experience and is also beneficial to the SEO optimization of the website. However, it should be noted that optimizing website speed is an ongoing process. Only by constantly monitoring and adjusting optimization strategies can website speed be maintained at a high level. We hope that the specific code examples in this article can help you better optimize ECShop website speed and improve user experience and website performance.
